I'm having problems uploading and even viewing files in the File section of MODX Revolution 2.2.3-pl. When I try to upload a file, all I get is "Upload error". Nothing shows up in the Filesystem area, just a folder called Media that doesn't let me do anything. Any ideas of what might be going on?
As far as file system permissions go, all folders are set to 755 and all files are set to 644. I'm seeing this behavior logged in as admin/sudo. I just moved my installation of MODX from my local machine, where I believe it worked right, to a shared hosting environment, and that's where I'm seeing this issue.
There has been a recent update to 2.2.4-pl after reported problems with the file manager.
I'd recommend updating to 2.2.4-pl and check if the problem is still present.
